The story behind BP's production is more than just opportunity

Many would assert, with some degree of truth, that Brandon Phillips leads the National League in RBI (with 42 entering play on Sunday 5/26) because of increased opportunities.  Votto and Choo have done such an incredible job getting on base (ranking 1st and 3rd in all of MLB for that category so far), that Brandon has had a wealth of chances.

Most runners on base for 2013 National League batters:
1) Brandon Phillips - 170
2) Jay Bruce - 159
3) Hunter Pence - 150
4) Yonder Alonso - 145
5) Zack Cozart - 141

This list tells a couple different stories.  First off, the Reds' offense has been generating a ton of opportunities.  To have 3 of the top 5 in this category is pretty absurd.  However, production is much more than opportunity...because as we all know, the three Reds on this list have had very different levels of success when they've batted with runners on.

Among the 125 batters in MLB who have had at least 100 runners on this season, Brandon ranks 13th in percentage of those runners driven in (20%).  Bruce rates a respectable 15.72%, good for 57th on the list.  Cozart is near the bottom - 109th at only 10.64% of runners driven in.  If you haven't considered this particular statistic before, I would summarize it as follows:

< 9% = terrible
9-11% = poor
12-14% = mediocre
15-17% = good
18-20% = excellent
>20% = outstanding

For his career, Phillips has been a good (but usually not great) producer with runners on.  Here are the percentages, rounded off to the nearest whole numbers:

2006 - 15%
2007 - 14%
2008 - 15%
2009 - 17%
2010 - 12%
2011 - 16%
2012 - 15%
2013 - 20%

Two years stand out - 2013 for success, and 2010 for lack thereof.  The biggest thing that can help you succeed in these situations is extra-base hits.  According to Fangraphs numbers, BP's 2010 isolated slugging percentage was only .155 (third-worst of his Reds career), while he's at .189 this season (second-best).  

At his current pace, Brandon would accumulate 40 doubles (a career high) and 26 homers (second only to his breakout 2007 season).  

Will he sustain this production level?  Maybe not.  But his improved approach and skill at the plate will certainly give him a good chance.  A number of his XBH this season have punctuated lengthy at-bats where he fouled off pitches until he got one to deliver into the gap (or the seats). While his overall pitches seen per plate appearance stat (about 3.7) has not changed this year, he makes the adjustments necessary in big situations, and quite visibly relishes the role of dependable RBI man.

Here's hoping that Brandon keeps it going, because he's on pace for some history.  Only Joe Morgan has ever driven in 100 runs in a season as a Reds second baseman, and he did it just once, with 111 in 1976.  BP is on pace for 138 RBI - that would be the 5th highest single-season total ever by any second baseman in major league baseball.
